I was a strong supporter of and believer in Trent in the beginning. Going into last night, I was among the majority of fans that was looking for Brohm to outshine #5. However, Edwards came up big when he had to, especially (as you mentioned) after taking a serious hit. So give Trent credit and hopefully he can continue to mature and improve.
I also give credit to Chan Gailey for handling this situation so far. Apparently he made up his mind after film review and OTA's that Trent was his best option. Following T.E.'s poor performance against Washington, Gailey didn't F with Trent's confidence by relegating him to second string in practice or the Indy game. He stuck with Edwards and publicly called out the O-line. Good move on Gailey's part. However one good PS game that included a 70 yard TD pass doesn't mean that Trent has finally arrived. He has to show improvement and consistency on a regular basis.
